SURFACE-FINISHING MACHINE FOR PAPER; I

Specification of Letters mat.

Application filed March 16, 1914. Serial N0.'824,847.

T0 alt whom it may concern V Be it known that I, HENRY P. HOWE, a citizen of the United States of America, and resident of I-Iolyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Surface-Finishing Machines for Paper, of which the following is a full, clear, and exact description. 7

This invention relates to a machine for the finishing of paper, and particularlyto improved means for imparting a cloth-like surface finish to the paper while being run in web form therethrough.

The invention, furthermore, relates to means comprised as a part of the machine or apparatus for the drying of the paper which is subjected to the surface finishing action in a somewhat moist condition, but which emerges from the machine entirely dry, and calendered as well.

Inasmuch as it is impracticable in machines for imparting a cloth-like finish to the surface of paper to employ cylinders on which the cloth covering thereof entirely surrounds the cylinder, owing to the fact that a seam mark would be necessarily made across the web, it is necessary to cover but part of the periphery of the cylinder with the cloth which is held thereon in tight or stretched condition by having theend portions thereof carried within recesses or re duced peripheral portions of the cylinder;

and the principal object of this invention is to so combine and arrange the cylinders, having coiperative cloth finishing Surfaces comprised in a portion of the circumference of each cylinder, in sets, that those of one set are operable to impart the surface finish ing to the running web in separated portions in the length thereof, while a succeeding Set of the cylinders imparts a surface finishing to the portions of the web which are intermediate between the portions finished by the preceding set of cylinders.

Another object of the invention is to pro vide means whereby under the rotations of the cylinders when the reduced portions of the adjacent ones are brought around together, the cylinders will be prevented from approaching each other to cause hammering action thereof to result in undue weal,

noisy action and impairment of the machlne. Another obgcct of the inventlon is to procomprised in the remainder of the driven at aslightlylessened surface speed Patented Mar. 2, 1915.

than that of thecylinders which impart the cloth-like finish to. the paper to compensate for the shrinkage of thelatter. And other ObJBClZS are to generally improve and Simplify the'construction of the machine to the end of increased efficiency, durability and the avoidance of liability of derangement after protracted use. a

The invention is describedin conjunctio with the accompanying drawings and is Set forth in the claims. I

In the drawings :Figure 1 is a plan view, and Fig. 2 is a side elevation of the improved paper surface finishing machine. Fig. 3 is .asectional elevation through a portion of the machine, on a larger scale, as taken on line 33, Fig. 1. -Fig. 4 is a cross ectional View on line 4 -.L, Fig. 1. Fig. '5 1s an end view of one of the cylinders. '1 Figs. 6, 7, 8 and 9 are dia-grammatical views to show asplainly as possible the mode of action of successive sets of the surface finishing cylinders. n

Similar characters of reference indicate corresponding parts in all of theviews.

In the drawings :-A represents the framing of the. machine, the oppositeside portions of which have horizontal longitudinally extending straight edged recesses a in which are slidable journal boxes B for the several cylinders whichperform the cloth- E h cylinderzhas a surface finishing pe we ripheral face 5 comprising a circumferential portion thereof and a reduced portion d perlmeter of the cylinder. In practice the full or truly circumferential portion Z) of each cylinder extends around the latter for slightly more than a full half of the perimeter and the cloth covering 6 overlies the full portion of the cylinder and is--extended within the reduced opposite portion of the cylinder, engaged with the tensioning rod disposed within the cavity d within the reduced portion (Z,theends of the cloth being in such winding engagement with the rod that by the rotation thereof the cloth may be tensioned in the proper degree. The rod is provided with a ratchet wheel 7 coacting with which is a spring pressed pawl f for maintaining the security of the cloth covering 111 its tensioned condition.

The cylinders of each set have their cooperative surface finishing full peripheral faces comprising approximately the half circumference all faced the same way, while the cooperative faces of the next set are in reversed relation to the corresponding faces of the cylinders of the first set as 13 fully shown in Figs. 2, 3, and 6 to 9.

The cooperative surface finishing faces of one set of the cylinders are effective for imparting the surface finishing of the running web of paper in separated portions in the length thereof, while the succeeding set of the cylinders, in reversed relation to those of the first set (cylinders l, 2, and 3 being compared with cylinders l, 5 and 6) impart the surface finishing to the portions of the running web which are intermediate of the ortions finished by the first set.

All of the cylinders of the set are held in hard peripheral bearing as insured by the screw shafts D D, threading horizontally and longitudinally through the machine frame and having forcing engagements against the slidable ournal boxes of the first and last cylinders of the series,all of the intermediate boxes being slidable so that the cylinders journaled therein may be forced in such manner as to maintain the cooperative full peripheral finishing faces 0 in tightly contacting relations.

The springs g are applied, between the adjacent boxes, under considerable compression, and they prevent the approaching of the adjacent cylinders when their reduced and non-cooperative portions are brought around into conjunction.

The first and second sets of cylinders, 1, 2, 3 and a 5, 6, are effective for imparting repeated surface finishing actions to the separated areas in the running web.

By reference to the diagram, Sheet #3 of the drawings, it will be seen that the portions 02 of the paper is first subjected to pressure and surface finishing action between cylinders 1 and 2 and then again between cylinders 2 and 3. The portion m of the paper which has received repeated surface finishing actions between rolls 1, 2 and 3, thence in passing in relation to the rolls 4, 5 and 6,'is not acted upon by these rolls, but the portion m relatively interme diate of the paperfinished by the first set of cylinders receives repeated surface finishing first in passing between the coeperative faces of cylinders e and 5 and then again between cylinders 5 and 6.

In the diagrammatic views the portions,

of the paper represented by solid black and designated by m are those dealt with by the cylinders of the first set, while the portions of the paper represented by the separated lines and designated :0 are those dealt with by the cylinders of the second set. The arbors of all of the cylinders have intermeshing spur gear wheels G Liv, the entire train being driven by the spur gear H on the driving shaft J of the machine for which the pulley J and driving belt J are provided.

Forward of the surface finishing cylinders is a calender stack K, and forward of the latter is a drying apparatus comprising rotative drier drums L L,having gearing connections one with another, as usual, the paper being conveyed, after being let off from the roll at at the rear of the machine, and which roll is supported by the brackets 72. it through the surface finishing cylinders, thence to the top of and down through the calender rolls, and thence to and around the rotary drier drums.

The web provided in roll f rm and supported on the brackets 72, is usually in a more or less moist condition as having been taken from the Fourdrinier machine after being subjected to but partial drying. The lower one of the calender rolls is driven by having a pulley K on its arbor, driven by a belt K from a pulley K on a shaft K which is provided with a gear wheel K in mesh with one of the cylinder gears G. The drums of the drier receive rotation by one thereof having on the arbor or journal shaft thereof a pulley L driven by belt L from a pulley L on a shaft L which has a cone pulley L thereon. A reverse cone pulley L is afiixed on a shaft L which by gear L is in meshing engagement with one of the surface finishing cylinder gears G. The belt L runs around the r versed cone pulleys and the driving means described for the drier drums operated by connection with the driving means for the surface finishing cylinders is of such character that the surface speed of the paper while passing in more or less nearly dried and shrunk condition around the drier drums may be slightly reduced, the reduced running speed being sus ceptible of regulation by the adjustment of the belt L on the cone pulleys as manifest.

The springs g g in compression between the journal boxes of the surface finishing cylinders exert at all times a separating force on the cylinders, so that while their reduced portions are brought around to conjunction such reduced portions may not by any possibility be brought to contact to cause shock, noise, and injury to the web.

Although usually the cooperative full peripheral faces of the cylinders in sets and arrangement as described are overlaid by tightly drawn textile fabric, other covering material for such faces may be employed; and while in practice a finishing machine having two sets of cylinders, of three cylinders in each set, is efficient for satisfactory surface finishing results, the machine may be employed wherein the cylinders of the two sets, having the formation and arrange ment described, may be two to the set; or more than three to the set may be employed; and the number of the cylinders comprised in the one set need not necessarily bethe same as that comprised in the other set.
